Short answer: the Andover Audio SpinSub. It ranks #34 of 42 subwoofers by sound quality at $350; the Sonos Sub Mini ranks #35 and costs $499, so there is little reason to consider the other one.
What the Sonos Sub Mini offers: Independent CEA-2010 testing records 76.4 dB at 20 Hz and 100.4 dB through 40-80 Hz. The sealed enclosure with 2x 6” (152mm) driver is best suited to upper-bass support in a modest room. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects. The 305.1H x 230.1W x 230.1D mm cabinet and 6.4 kg mass still need deliberate placement and calibration.
What the Andover Audio SpinSub offers: Independent CEA-2010 testing records 101.4 dB through 40-80 Hz. The ported enclosure with 2x 6.5” (165mm) driver is intended to add useful bass support without a full-size cabinet. Watch for: Without a published 20 Hz output result, deep-bass capability is less certain than its midbass figure. The 361.9H x 285.8W x 323.8D mm cabinet and 9.5 kg mass still need careful placement and calibration.
Buy the Andover Audio SpinSub. It ranks higher for sound quality than the Sonos Sub Mini and costs less, so there is no real case for the other one.
Skip both if sound quality is the priority. There are better options higher up the 42 subwoofers.
